ABSTRACT:
A scroll fluid machine comprises a housing, a driving shaft, a fixed scroll fixed to the housing, and an orbiting scroll. A gas introduced from the outer circumference of the housing is compressed towards the center of the housing with revolution of the orbiting scroll by the driving shaft. The compressed gas is discharged through a discharge hole extending from the center outward in a radial direction. A silencer fits in the discharge hole to prevent noise caused by discharge of the gas.
